ABSTRACT
Objective To explore the clinical efficacy and application value of hemivertebra resection for treating congenital ky‐phoscoliosis .Methods 30 cases of congenital kyphoscoliosis and hemivertebral deformity in our hospital from January 2011 to Jan‐uary 2013 were selected as the research subjects .Among them ,12 cases of simple vertebral and non‐structural bending were per‐formed the posterior hemivertebral resection and short segment pedicle screw fixation ;3 cases of complicating lordosis and hemiver‐tebral protruding to the ventral side were performed the anterior hemivertebral resection and bone graft fusion fixation ;15 cases of complicating structural compensatory curve were performed the posterior transpedicle hemivertebral resection and compensatory bend long segment fixation and fusion .The clinical effects of surgical treatment for all patients were performed the comparative a‐nalysis .Results The mean postoperative kyphosis Cobb angle and the average final follow‐up Cobb angle were (8 .6 ± 3 .14) °and (11 .2 ± 7 .23) °respectively .The ultimate orthopedic rate of kyphosis was 58 .6% ;the average postoperative Cobb angle and and the average final follow‐up Cobb angle of scoliosis were (12 .8 ± 5 .47)°and (16 .2 ± 6 .24)°respectively ,the final orthopedic rate of scoliosis was 66 .5% .The mean Cobb angle of kyphosis and scoliosis after operation was significantly less than that before opera‐tion ,the difference was statistically significant(P< 0 .05) .Kyphosis and scoliosis were significantly improved .No significant post‐operative complications occurred .The effects were satisfied by the patients .Conclusion The hemivertebral resection has significant effect for treating congenital kyphoscoliosis with high kyphoscoliosis orthopedic rate and is worthy of further clinical study .
ABSTRACT
Congenital kyphoscoliosis is an abnormal curvature of spine that is due to presence of vertebral anomalies which cause an imbalance in the longitudinal growth of the spine. Congenital kyphoscoliosis is often rigid and its correction can be difficult. It is often resistant to conservative treatment and more patients require surgical treatment than those with idiopathic curvature. The indication for the conservative treatment with Milwaukee brace is much limited. Largely Milwaukee brace is a delaying tactic to correct the spinal curvature until its growth is further advanced and it is more amenable for fusion. This paper was aimed to review our experience with 49 patients with congenital scoliosis, kyphosis and kyphoscoliosis who were treated surgically with various methods of preoperative correction, from Jan. 1968 to Dec. 1983, in special reference to new classification, proposed for common application to both kyphosis and scoliosis, and following results were obtained. 1.The average age when scoliosis was observed was 6.9 years, but the average age of surgery was deferred until 15.2 years. 2. The distribution of curve pattems were 1 cervicothoracic, 24 thoracic, 12 thoracolumbar, 7 lumbar and 1 lumbosacral curve in 45 scoliotic curves and 13 thoracic, 13 thoracolumbar and 4 lumbar curves in 30 kyphotic curves. The average degrees of deformity were most severe in thoracolumbar curves both in kyphosis and scoliosis. 3. The new morphological classification, which could be applicable to both kyphosis and scoliosis, was proposed. The type of unsegmented bar with contralateral hemivertebra was most common both in kyphosis and scoliosis. 4. Preoperative average degrees of scoliosis was 58.7 degrees and final correction was 20.6 degrees (35.1%) with loss of comection of 3.7 degrees (6.3%). Preoperative average degrees of kyphosis was 63.7 degrees and final correction was 20.1 degrees (42.5%) with loss of correction of 7.0 degrees (11.0%). 5. The surgical method with anterior and posterior fusion was the best treatment of severe kyphoscoliossis, in the aspect of final correction and loss of correction. 6. The lumbar curve was most amenable to treatment with the best final correction and the least loss of correction.
